CONTROLLER.

SPECIFICATION forming part of Letters Patent No. 653,743, dated July 17', 1900.

Application filed J' anuary 9, 1899. Serial No. 701,599. (No model.)

To a-ZZ whom it my concern/.-

Beit known that I, WILLIAM M. JEWELL, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Controllers, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to controllers for regulating the flow of wateror other fluid through a conduit, and has for its object to provide a controller in which variation in the pressure of water in the conduit will act to enlarge or reduce the area of the discharge-passages in such manner as to maintain a substantiallyconstant flow.

To this end my invention, generally stated, consists in providing a conduit with a movable outlet-pipe through which the water or other fluid flows in its passage fromnthe conduit, said pipe being arranged to be moved by variation in the pressure of the water in the conduit, such movement effecting a variation of the area of the discharge ports or passages in such manner "as to increase the area when the pressure in the conduit is reduced and to reduce the area when such pressure increases.

My invention further comprises means for regulating the action of the controller, so that the normal flow may be varied. It also provides means whereby under certain conditions a greater movement of the outlet-pipe is necessary to effect a given variation of the area of the discharge-ports than at other timesthat is to say, where the water in the conduit is under considerable pressure the apparatus is arranged so that a greater movement of the outlet-pipe is necessary to effect a given variation in the area of the discharge-ports than when the water in the conduit is under lower-pressure, thisl arrangement being conducive to uniformity in the flow.

My invention also comprises certain details of construction which will be hereinafter particularly pointed out.

In the drawings, Figure 1 is a vertical section. Fig. 2 is a horizontal section on line 2 2 of Fig. 1. Fig. 3"is a plan view of the outlet-pipe. Fig. e is a view of the lower end thereof looking upward, and Fig. 5 is a plan view of the head at the lower end of said pipe.

Referring to the drawings for a particular description of my invention as therein illustrated, 6 indicatesa conduit or pipe having a chamber 7 communicating therewith and forming an extension thereof. The shell 8 ot' the chamber 7 is preferably secured to the pipe 6 by bolting it to a coupling 9, as illustrated 'in Fig. 1; but it may be otherwise arranged, if desired. Above the chamber 7 is a chamber 10, which communicates with a second conduit 0r delivery-pipe 11, as shown in Fig. 1.

12 indicates an annular flange formed in the casing 8, which flange separates the chambers 7 and 10 when the parts of the controller are assembled as illustrated.

13 indicates a cap which tits over the upper end of the casing 8 and is firmly secured thereto.

14 indicates an outlet pipe or valve which is fitted in the shell 8, its Lipper end iitting snugly in a ange 15 at the upper end of said shell, the intermediate portion of said outletpipe having a bearing in the flange 12. At its lower end the pipe 14 is provided with a peripheral flange 16, which extends to the wall of the chamber 7. The pipe 14 is longitudinally movable in the shell S, and when in its lowermost position rests upon a flange 17, preferably formed on the coupling 9, as shown in Fig. 1. The flange 16 is 4provided with a number of orifices or passages 18, through which water is admitted from the conduit 6 to the chamber 7.

19indicatesaplurality of segmental blocks which project below the tlange 16, being substantially continuations of the outlet-pipe 14.

2O indicates ahead which lits upon the lower end of the outlet-pipe 14, bearing against the lower edges of the blocks 19, as shown in Fig. 1. The head 2O is provided with segmental blocks 21, which are adapted to fit within and bear closely against the segmental blocks 19, the blocks 19 and 21 being so arranged relatively to each other thatthe blocks 21 when moved to the proper position by the rotation of the head 2O close the spaces between the blocks 19. By this construction, therefore, the area of the passages 22 between the head 2O and the lower end of the outlet-pipe 14 may be varied. For the purpose of rotating the head 20 to adjust the size of the pas- IOO Vit.

sages a rod 23 is provided, the lower end of which is connected to the head 20, its upper end being fitted in a bearing in a spider 2i, as shown in Fig. 1. The upper end of the rod carries a nut 25 which screws upon it and serves to hold the head 2O up in operative position, and also as a means of rotating said rod 23. Said rod also carries a pointer 26 to indicate the position of the head.

As shown in Fig. 1, the outlet-pipe .11 is provided with one or more ports or dischargepassages 27, arranged to communicate with the chamber 10. In the best form of my invention the ports 27 are tapered in form, being of greatest width at the top and gradually diminishing in width to the bottom.

The operation of my improved controller is as follows: The water or other fluid rises through the conduit 6 and thence flows around the edges ot' the head 20 through the passages 22 into the outlet-pipe 14, thence rising through said pipe and being discharged through ports 27 into the chamber 10, whence it iiows through the delivery-pipe l1. When the parts are in the position shown in Fig. l, the ports 27 are wide open, the pressure of the water in the conduit 6 being at the lowest point. Assuming that with the segments 19 21, arranged as shown in Figs. 1 and 2, the desired fiow of water is provided when the pressure is at the minimum should the pressure of the water in the conduit 6 increase, the increased pressure will be partially directed against the under side of the head 20, causing it to rise, raising the pipe 14C and partially closing the ports 27, inasmuch as the upper ends of said ports will pass above the Ylower edge of the flange 15 and be closed by This decrease in the area of the dischargeports 27 reduces the discharge, and consequently causes a back pressure, which neutralizes the excess of pressure in the conduit 6 beyond what is required to raise the discharge-pipe. When the pressure in the conduit 6 is reduced, the discharge-pipe 14 is permitted to drop, again increasing the area of the ports 27. By this means whatever variations may occur in the pressure of the water in the conduit 6 do not materially aiect the low'of water through the pipe 14. and conduit 11, which is maintained at practically a constant point. lVhen the pressure in the conduit 6 is greatly increased, the pipe 121 is raised to a higher point, as above described, the wider portions of the ports 27 being closed, the water being discharged from the pipe 14 through the narrower lower portions of said ports, and, as it is evident that the pipe 14 must move a greater distance when in such position in order to effect a given variation in the area of the ports 27 than is the case when it is at its lowermost position the result is that when the water is under high pressure, at which tifme it is more subject to sudden variations, the greater movement of the pipe 14:, caused by such varations in the pressure, does not materially aect the outiiow. To vary the ow, the head 20 is adjusted to vary the area of the passages 22.

When the controller is in use, water ows through the orifices 18 into the chamber 7, forming a cushion for the pipe 14, preventing violent action thereof, and causing it to move gradually when moved in either direction.

It will be understood that the specific construction above described may be varied without departing from my invention, as various modifications of the apparatus described may be made.

InA the spec'ilicati'onand claims I have used the term outlet-pipe7 in describing the part 14; but it should be understood that I do not thereby limit myself to the use of a pipe proper, as the term as therein used includes also any conduit through which the fluid is passed for the purpose ot' controlling its iiow and by the movement of which the flow is regulated. It will also be understood that while this apparatus is intended particularly for use in controlling the flow of water, it may be used for controlling fluids gener ally,7 by which term I mean to include gases as well as liquids;
